处理Durandal应用程序中视图的加载超时 [英] Handling load timeouts of a view in a Durandal app

问题描述

我有一个Durandal应用程序，在尝试加载视图时会定期超时。这是一个示例超时错误：

I've got a Durandal app that will periodically timeout when attempting to load a view. Here's an example timeout error:

Error: Load timeout for modules: text!views/primaryapplicants.html
http://requirejs.org/docs/errors.html#timeout

如果您查找提供的网址，建议一些可能的问题：

If you lookup the provided URL, it suggests a few possible issues:

• 列出的模块中的脚本错误


• 路径配置不正确


• 多个模块ID映射到同一个文件

这些都不是我的问题。这是一个真实的，真正的超时。由于某种原因，它无法加载视图文件。

None of these are my issue. It is a real, genuine timeout. For some reason it wasn't able to load the view file.

有一些有关处理错误的RequireJS文档 ...但在阅读了很多次之后，我仍然无法弄清楚如何在我的视图模块上捕获加载超时。

There is some RequireJS documentation on handling errors... but after reading it a number of times, I still can't figure out how to trap for a load timeout on my view module.

理想情况下，我想做的是a）延长超时或b）给用户一个通知并允许他们再次尝试加载视图。

Ideally, what I would like to do is either a) extend the timeout or b) give the user a notification and allow them to try loading the view again.

现在发生的事情是视图无法加载，用户没有得到错误的反馈 - 请等待，加载对话框消失，因为AJAX请求已完成，但视图没有改变。

What's happening right now is that the view simply fails to load and the user gets no feedback that there was an error--the "please wait, loading" dialog disappears because the AJAX request finished, but the view doesn't change.

推荐答案

我有时遇到同样的问题。对我来说，它通常发生在另一个异步请求阻塞服务器时（在我的开发机器上一次只能处理一个请求）并且请求了一个视图。

I sometimes have the same issue. For me, it usually happens when another asynchronous request is blocking the server (that can handle only one request at a time on my dev machine) and a view is requested.

我还不知道怎么抓住这个，但是为了增加/禁用超时：

I don't know yet how to catch this, but in order to increase/disable the timeout:

requirejs.config({
    waitSeconds: 0 // 0 disables the timeout completely, default is 7 seconds
});
